That single bay reservoir is the - Bitspower 5.25" Bay Reservoir - Black (BP-WT525P-BK) Now I'm struggling to find a place to buy this in the UK. I have seen it on Frozen CPU and a few other American sites. Anybody seen it on an English store? Or I guess the cheapest place to ship it to England. Europe would be better than the US I imagine! Any help would rock. Thanks guys.
